Therefore, based on the key project ? esearch on some basic problems on quality control and source tracing in modern manufacture ? ( no. 59735120 ) sponsored by national natural science foundation, a deep research is made in this dissertation its branch subject ? the theory and technology of zero - waste control. the main work and achievements are as follows : 1. on the basis of the introduction of common quality control methods, some key problems about statistical quality control are elaborately discussed ; a method to decide the quality control line is developed ; a mathematical model based on the sampling plan of multi - variation of product quality is set up ; the process manufacturing condition of quality control chart is discriminated using the theory of fuzzy diagnosis
為此，本文基於國家自然科學基金重點資助項目「現代製造質量控制、溯源若干基礎問題的研究」 （項目編號： 59375254 ） ，重點對其中的子課題? ?零廢品控制理論和技術進行了深入的研究。論文的主要工作和取得的成果如下： 1在介紹了常用質量控制方法的基礎上，對統計質量控制的幾個關鍵問題進行了詳盡的討論，提出了質量控制界限的確定方法，建立了基於產品質量多變異的抽樣方案的數學模型，利用模糊識別理論對質量控制圖工序加工狀況進行了判別。 -
Abstract : a new current feedback control method of brushless dc motor ( bldcm ) is introduced in this paper, which combines the traditional overlap method with the fixed - frequency sampling current control method. it both stabilizes the work frequency of the inverter, and improves the commutative performance of bldcm. and it is verified by the result of the simulation
文摘:提出一種永磁無刷直流電機電流反饋新的控制方法，即採用常規重疊換相法與定頻采樣電流控制相結合的方法，既能穩定逆變器的工作頻率，又改善了永磁無刷直流電機的換相性能，利用模擬對提出的方法進行了驗證。 -

The majority of work that is presented in this thesis is listed as follow : the most problem of two - terminal fault location method is that the sampling of two - terminal dates is unsynchronized. thus this thesis presents a new unsynchronized technique for two - terminal fault location
全文主要工作如下：雙端故障測距法所面臨的主要問題是兩端數據采樣的同步問題，針對這一問題，本文提出了一種不需要兩端數據采樣同步的工頻故障測距新方法。 -
In the time - interleaved adc system, m pieces of adcs work in a parallel method and sample at a sampling frequency fs / m, in the back - end of the system, m outputs are multiplexed to give an overall sampling frequency f s
這種方法在前端利用m片adc并行交替采樣，在後端進行拼接使得整個採集系統的速率為m片速率之和。
